Now u buid a rail that can accomodate say 22 mln tonnes a year then u bought locomotives n wagons with axle load 25 tonnes! and worst enough none of the engine can pull 100 wagons! Mind u the SGR is a single line! Huu ndio ufalamanga naokuambia kila siku! BTW according to today's report that SGR costed $5 bln and not $4.3 bln as was said before!
You continue to show just how much you don't know....
1.Less axle load means more frequencies, more axle means less frequencies.
2. Ethiopia has double line for 105km but you know how we manage to have more carrying capacity than them? We have line 33-40 loop lines /passing stations just between Msa-Nrb alone, What that means is when timed/scheduled to the minute, trains can pass each other on the single track stopping for only 5 mins (with passenger trains given right of way) ---- That means we can achieve the same effect as having half the distance with double lines.
I have told here before there is something called "Operations Research" ... Just because something make sense in your small head doesn't make it true.... You actually have to do some complex calculations...
Lets say it takes 3 hours to fill up one Tanzanian 10,000 tonnes train, and it takes one hour to fill one Kenyan 4,000 ton train... By the end of the first hour, one of the Kenyan trains would be full and will leave for its destination, by the end of the second hour the next Kenyan train will also leave and have a head start, By the end of the 3rd hour, the Tanzanian train will now be full, but so will the 3rd Kenyan train... and since the Tanzanian Train is slightly faster it will reach its destination earlier.... But the first two Kenyans trains would have already reached their destination and started unloading cargo by then, and once they are done, they will start going back to pick more, By the time The Tanzanian train reaches its destination and starts unloading cargo, the third Kenyan train will get there before or less than an hour after you have unloaded all the cargo and at the end of the day, 3 Kenyan trains would have delivered 12,000 tonnes, while 1 Tanzanian Train would have delivered 10,000 tonns..... At the end of the year that will be 4,380,000 for Kenya and 3,650,000 for Tanzania...
👆👆 That is just but a simplistic example of how you end up with results which you never imagined when you tried to just think about such things without using a formula to calculate
